Prevalence of infections of the ascitic fluid in 81 consecutive cirrhotic patients

During a period of 30 months the ascites of 81 patients with liver cirrhosis (65 males and 16 females; 25 in Child B class and 56 in Child C class) consecutively admitted to an Internal Medicine Department have been examined. The number of polymorphonuclear leukocytes (PMNs) and the protein content of ascites were evaluated, and cultures for aerobic and anaerobic bacteria were performed. In 46 patients ascites were sterile (SA); bacteriascites (BA) was observed in 3 patients; neutrocytic ascites (NA) in 18 patients; spontaneous bacterial peritonitis (SBP) in the remaining 14 patients. The number of PMNs and total protein content turned out to be significantly higher and lower respectively in SBP compared to the other groups (p < 0.02). In 10 out of the 17 patients with BA and SBP bacteria of enteric origin were isolated. Total mortality was 23.5% (4 cases).
